Tudeskie:
I was able to get a 192x64 display working with your code that you do not have listed in the docs. What is the best way for me to send you the setup info so it can get added into the documentation?
There is a 192x64 configuration file that ships with the library. Did you have to modify that?
If so, it would be useful to get the changes that you made.
There are some specific modules mentioned on the ks0108 playground wiki page including some 192x64 displays.
You can modify the wiki page to include information about your specific display.
